Independent verification
Every batch is tested by Janoshik Analytical (Czech Republic, HPLC + MS) and Aethos Bioanalytics (US, independent HPLC + LAL endotoxin where applicable). Both Certificates of Analysis are published on this product page — never edited, never curated. If the two labs disagree on purity by more than 0.5%, the entire lot is destroyed.
